Typical climate through the year
Swansea has a temperate oceanic climate, strongly influenced by the Atlantic. Average daytime temperatures in summer (June–August) range from 16 °C to 20 °C, with occasional warmer spells above 25 °C. Winter highs (December–February) sit between 7 °C and 9 °C, while overnight lows can fall to 2 °C or slightly lower. Rainfall is spread throughout the year, with autumn and winter tending to be wettest – expect around 120–140 mm per month in November and December. Spring and early summer are drier, with April and May averaging about 60–80 mm.
How does Swansea’s coastal location affect the weather?
Being on the south coast of Wales, Swansea benefits from the moderating effect of the sea. Winters are less cold than inland Welsh towns, and summers are rarely excessively hot. However, the same maritime influence brings frequent cloud and drizzle, especially when south-westerly winds push fronts onshore. The Gower Peninsula can create its own microclimates – the southern coast of the peninsula often enjoys drier conditions than the city itself. For official warnings of heavy rain or strong winds, check the UK weather warnings page.
Best time of year to visit Swansea
Late spring (May to June) and early autumn (September) offer the best balance of milder temperatures and lower rainfall. July and August are warmest but can be busy and occasionally humid. Pack layers, a waterproof jacket and sturdy footwear – even in summer a light raincoat is sensible. Sea temperatures peak around 16–17 °C in August, making it possible for coastal walks and beach visits.
